Summer is officially over. The lab notebook tells me so.Larry brought his microscope home from school in order to prepare his lesson plans, and he has been geeking out since seven o’clock this morning. I'm glad he's passionate about his work, but our house was a lot cleaner when he taught English.There are leaves and skins and other wet specimens everywhere, and he has called me into the kitchen at least seven times to “CHECK OUT THESE CELLS!”I was in the bedroom taking a nap when he burst in, arms flailing, and said, “I have just witnessed fagocytosis!”“So have I,” I said, pulling the covers over my head.Of course there is a small part of me that finds his inner mad scientist sort of cute. But you'd probably need a microscope to see it.
